Creative Filters: Polariser

Achieving creative effects using polarising filters.
These devices filter out light that is polarized in a specific direction. They are used to reduce reflections from surfaces and to darken the sky. They can be used to photograph objects through glass and water.
Please read all of the additional rules carefully - during the first challenge I disqualified nearly half of the entries because they did not include details of the type of filter used to achieve the shot.
In some photographs, the use of a polariser may not be readily apparent. For the purposes of this challenge, it should be clear to an informed observer that your photograph was enhanced by the use of the polariser.

Processing rules:

Post-processing is allowed, but the main creative effect in your photograph must have been achieved by the use of a polarising filter.

Capture date rules:

No restrictions.

Additional rules:

1) You MUST state the type of filter used, including the brand (eg: B+W MRC Kaesemann). If you do not, then your entry will be disqualified.

2) You SHOULD state how you used your filter to create the effect in your shot. If you do not do this, it may not be clear to the casual observer why your photo is a good example of polariser use.

Your complaint (along with the complaints of others regarding this entry) will be
reviewed by the challenge owner. Depending upon the nature and applicability of the
complaint, the entry may be disqualified. In extreme circumstances the user who submitted
the entry may receive a ban from the challenge or series in question.
